From 9cc63f8bcd560c760d0b12e15bba8f81c86237cf Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 14 Aug 2026 15:43:51 -0700 Subject: Merge branches 'expcb.2026.07.24a', 'misc.2026.07.30a', 'rcu-tasks.2026.07.30a', 'srcu.2026.08.11a' and 'torture.2026.08.14a' into HEAD Changes: Make expedited grace periods expedite normal RCU callbacks Miscellaneous fixes: * Improve diagnostic output with character task states. * Mark accesses to inform KCSAN of concurrency design. * Move from kmalloc() to kmalloc_obj(). * Documentation updates. * Improve handling of RCU deferred quiescent states. * Clean up unused function arguments and structure fields. * Reduce show_rcu_gp_kthreads() stack space. Tasks RCU updates: * Clean up after SRCU re-implementation of Tasks Trace RCU. * Mark accesses to inform KCSAN of concurrency design. * Add ->lazy_timer status to diagnostic output. * Remove an unnecessary memory barrier. * Fix a data race, courtesy of KCSAN. * Documentation updates. * Convert cond_resched_tasks_rcu_qs() from macro to static inline function. SRCU updates: * Add Rust helpers for SRCU. * Avoid losing queued work at cleanup_srcu_struct() time. Torture-test updates: * Preparation work for immediate RCU priority deboosting. * Test RCU readers from real interrupt handlers (as opposed to softirq). * Simplify code through use of cpumask_next_wrap(). * Improve diagnostic output with character task states. * Add rcutorture.nwriters parameter to allow lightweight stall testing, and rcutorture.stall_only to make doing so easier. * Test an RCU Tasks Trace grace period implying an RCU grace period. * Make RCU Tasks Trace torturing track reader batches. * Fix a data race, courtesy of KCSAN. * Plug a shuffle_tmp_mask memory leak on kthread spawn failure. --- drivers/accel/rocket/Kconfig | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 drivers/accel/rocket/Kconfig (limited to 'drivers/accel/rocket/Kconfig') diff --git a/drivers/accel/rocket/Kconfig b/drivers/accel/rocket/Kconfig new file mode 100644 index 000000000..16465abe0 --- /dev/null +++ b/drivers/accel/rocket/Kconfig @@ -0,0 +1,24 @@ +# SPDX-License-Identifier: GPL-2.0-only + +config DRM_ACCEL_ROCKET + tristate "Rocket (support for Rockchip NPUs)" + depends on DRM_ACCEL + depends on (ARCH_ROCKCHIP && ARM64) || COMPILE_TEST + depends on ROCKCHIP_IOMMU || COMPILE_TEST + depends on MMU + select DRM_SCHED + select DRM_GEM_SHMEM_HELPER + help + Choose this option if you have a Rockchip SoC that contains a + compatible Neural Processing Unit (NPU), such as the RK3588.
